Abstract :
Terahertz (THz) generation, using the Difference Frequency (DF) effect, is a promising way to develop a THz source. Dual-wavelengths laser, having stable phase and with a spacing of 3 nm centered around 1550 nm, are emitted from the same fiber ring laser. A tunable THz frequency component is demonstrated by tuning the FBG inside the laser cavity.
